Description

Silicon Laboratories’ Si4032/31/30 highly integrated, single chip

wireless ISM transmitter is part of the EZRadioPRO™ family. The

EZRadioPRO family includes a complete line of transmitters,

receivers, and transceivers allowing the RF system designer to

choose the optimal wireless part for their application.

The

continuous

adjustable output power of up to +20 dBm with the Si4032. The

Si4030 offers frequency coverage from 900 to 960 MHz to support

the Japanese frequency bands. The Si4032 delivers a maximum

output power of +20 dBm programmable from +11 to +20 dBm in

3 dB steps. The Si4031/30 delivers a maximum output power of

+13 dBm programmable from –8 to +13 dBm. The Si4032/31/30’s

high level of integration offers reduced BOM cost while simplifying

the overall system design. The Si4032’s Industry leading +20 dBm

output power ensures extended range and improved link

performance.

Additional system features such as an automatic wake-up timer,

low battery detector, 64 byte TX FIFO and automatic packet

handling reduce overall current consumption and allow the use of

lower-cost system MCUs. An integrated temperature sensor,

general purpose ADC, power-on-reset (POR), and GPIOs further

reduce overall system cost and size.

The transmitter supports automated packet construction, allowing

data to be streamed from the TX FIFO without external MCU

support. The PA is single-ended to allow for easy antenna

matching and low BOM cost. The digital transmit modulation and

automatic PA power ramping ensure precise transmit modulation

and reduced spectral splatter, ensuring compliance with FCC and

ETSI regulations. The Si4030 is designed to ensure compliance

with ARIB regulations. The Si4032/31/30 is designed to work with

an MCU, crystal, and a few passives to create a very low-cost

system. Voltage regulators are integrated on-chip, which allows for

a wide range of operating supply voltage conditions from +1.8 to

+3.6 V.
